In sensitive application areas, such as medical, communications, automotive and aerospace technology, reliability of the underlying electronic systems is of utmost importance. Therefore, the semiconductor industry and manufacturer of electronic components and systems carry out thorough electrical tests on their products, in order to guarantee their failsafe operation. One important aspect is testing the ESD (electrostatic discharge) tolerance of the chips, since miniaturization of semiconductor components makes them more prone to damage due to electric impulses caused by electrostatic discharge.
